Procedure

By following the same procedure as Example 20 (2nd step) except that 17.5 g of N,N-dimethylpyrrolidinium methyl carbonate, 17.5 g of water, and 9.8 g of maleic anhydride were used, 21.4 g (yield of 99.6%) of N,N-dimethylpyrrolidinium maleate was obtained. The content of mono-maleate was less than 0.1% and the contents of impurity ions were less than 1 ppm.
